Description

Technical Field

[0001] The various embodiments disclosed in this specification relate to an automatic rotating device for toddlers, and more specifically, an automatic rotating device for toddlers that can automatically rotate a rotating object. Background Technology

[0002] It is generally believed that infants can distinguish between black and white about one month after birth, and then they will react to simple sounds and colors. After a period of time, they will react to repeated sounds and colors, and gradually react to complex sound and color changes.

[0003] As a result, various children's products have emerged that help develop children's attention and emotions, one of which is the toy for toddlers to spin.

[0004] Ordinary spinning toys for toddlers attract their attention by shaking when subjected to external forces or being blown by the wind. However, in the past, these toys could only shake, which meant that toddlers would quickly become bored with them.

[0005] Therefore, in recent years, a technology that uses the rotational force of an electric motor to make it rotate automatically has been disclosed, such as the upright rotating toy for toddlers disclosed in Korean Patent Publication No. 10-2012-0006604.

[0006] However, the problem with the prior art as described above is that since the rotating toy attached to the rotating toy stand is rotated only by the uniform rotational force of the rotating motor, young children may not be able to concentrate and may easily lose interest.

[0007] In addition, since the prior technology only attracts young children's attention by rotating the toy, it can easily lead to boredom in young children.

[0008] Therefore, a technology is needed to solve the above problems.

[0009] On the other hand, the aforementioned background technology belongs to the technical information that the inventor of the utility model already possessed in order to obtain the utility model or that was mastered during the research and development of the utility model. Therefore, it cannot be regarded as publicly known technology that was disclosed to the general public before the application for the utility model. Utility Model Content

[0047] The various embodiments will now be described in detail with reference to the accompanying drawings. The embodiments described below can also be modified to achieve other different forms. To more clearly illustrate the features of the various embodiments, content widely known to those skilled in the art to which the following embodiments pertain will not be described in detail. Furthermore, parts unrelated to the description of the embodiments are omitted from the figures, and similar reference numerals are used for similar parts in the specification.

[0049] Several embodiments are described in detail below with reference to the accompanying drawings.

Figure 8 This is a schematic diagram showing the usage of an automatic rotating device for toddlers according to an embodiment. Figure 9 and Figure 10 This is a schematic diagram showing the start-up state of an automatic rotating device for toddlers according to an embodiment.

[0051] According to one embodiment, the automatic rotating device 10 for toddlers is as follows: Figure 8 The diagram shows a device that automatically rotates multiple rotating objects 1, thereby improving children's concentration.

[0052] Specifically, one embodiment of the automatic rotating device 10 for toddlers, such as... Figures 1 to 3 As shown, it may include a base portion 100, a head portion 200, a drive portion 300, a first rotating plate 400, a rotating plate 500, and a second rotating plate 600.

[0053] The base portion 100 is manufactured to a predetermined height and serves as a component for supporting the rotating object 1 at the predetermined height while providing support.

[0054] This base portion 100 may include a base plate 110, a vertical rod 120, and a connecting rod 130.

[0055] The base plate 110 is formed in the shape of a plate with a predetermined area and can be supported on the ground.

[0056] The vertical rod 120 is attached to the base plate 110 in a vertical state, providing a fixed position for the connecting rod 130 (described later) and ultimately used to adjust the height of the rotating object 1.

[0057] Specifically, the vertical rod 120 is made into a straight line with a predetermined length. One end of the rod is fixed to the base plate 110 in the length direction, while the other end can extend in the vertical direction, forming a plurality of fastening holes 121 at predetermined intervals along the length direction.

[0058] This vertical rod 120 is fixed with one end clamped into a portion of the base plate 110, unlike the other rod which can be fixed with a separate fixing member as the medium.

[0059] The connecting rod 130 is a component that connects the vertical rod 120 to the head 300 (described later) and supports the head 200 in an inclined state.

[0060] Specifically, the connecting rod 130 is made into an arc shape with a predetermined length and a predetermined curvature. One end of the two ends in the length direction is connected to one of the fastening holes 121 of the vertical rod 120, and the other end is connected to the head 200 described later, thereby supporting the head 200 to form an inclined state corresponding to the curvature.

[0061] Here, the connecting rod 130 is such that one end is fixed to one of the fastening holes 121 of the vertical rod 120 by a component such as a fastening bolt, while its height is adjustable. According to the embodiment, for example... Figures 1 to 4 As shown in the figure, the music box 150 can also be fixed to the fastening hole 121 of the vertical rod 120.

[0062] This music box 150 is a component that provides music by switching the power supply on and off, while also being connected to the fastening hole 121 of the vertical rod 120 and providing a fixing part for the connecting rod 130.

[0063] Specifically, the music box 150 can be fixed to the vertical rod 120 by a fastening member 155 that protrudes from a portion of the bolt portion and forms an internal thread that is fastened to the bolt portion in the state of clamping into the fastening hole 121, and a fixing part for the connecting rod 130 is provided by the connecting hole 151 formed at the upper end.

[0064] This music box 150 can be equipped with multiple control buttons for playing different music, and can also be equipped with control buttons for turning the nursing lamp 250 (described later) on and off.

[0065] Subsequently, while the connecting rod 130 is fixed to one of the fastening holes 121 of the vertical rod 120 via the music box 150, the height of the conversion object 1 is adjusted.

[0066] The head 200 is a component that provides mounting space for the drive unit 300 (described later) and also provides a joint between the first rotating plate 400 and the second rotating plate 600 (described later).

[0067] This head 200 is like Figure 2 and Figure 4 As shown in the figure, the first rotating plate 400 and the second rotating plate 600 can be rotated by being attached to the upper end of the connecting rod 130.

[0068] Specifically, the head 200 such Figure 5 and Figure 6 As shown in the figure, the container is made into multiple separate containers, which can provide an installation space for the drive unit 300 to be installed inside. A boss 210 is provided at the front end to form the rotation center of the first rotating plate 400 and the second rotating plate 600, so that the first rotation axis 410 of the first rotating plate 400 and the second rotation axis 610 of the second rotating plate 600 are rotatably connected to the boss 210.

[0069] Here, the head 200 is, for example, the connecting rod 130, which can be fixed in a direct connection manner, according to the embodiment, such as Figure 4 As shown in the figure, the angle can be adjusted while the connecting rod 130 is fixed by using the angle adjustment joint 140 as a medium.

[0070] This type of angle adjustment connector, such as Figure 6 As shown in the figure, it is formed in a cylindrical shape, and a connecting hole is formed at the lower end of the head 200 to provide a fixing part for the connecting rod 130, which is rotatably set in the head 200, and allows the head 200 to rotate in the up, down and left and right directions, thereby adjusting the angle of the head 200.

[0071] Subsequently, the angle adjustment joint 140 adjusts the angles of the first rotating plate 400, the second rotating plate 600, and the rotating plate 500 connected to the head 200 by adjusting the angle of the head 200.

[0072] On the other hand, the top 200, such as Figure 5 As shown in the figure, the rear end can be opened and closed by a cover 220, and the inside of the cover 220 can be provided with a nursing lamp 250 to provide illumination during nighttime breastfeeding.

[0073] Here, the nursing lamp 250 provides illumination by turning the power on and off via a control button located on the music box 150 or the head 200, and the cover 220 can be made of a translucent material so that the illumination can be transmitted.

[0074] In addition, the nursing lamp 250 can also be installed on the base 100, in addition to the head 200, to provide illumination by turning the power on and off.

[0075] The first rotating plate 400 is attached to the boss 210 of the head 200, and is a component that rotates around the boss 210 when the drive unit 300 (described later) is activated, thereby causing the rotating plate 500 (described later) to rotate.

[0076] Specifically, in the first rotating plate 400, such as Figure 5 As shown in the figure, it is made into a circular plate of a predetermined size and is rotatably connected to the boss 210 of the head 200 via a first rotating shaft 410 protruding from the back, and then connected to the drive unit 300.

[0077] Here, the first rotating plate 400 is formed with the first rotating shaft 410 in an eccentric state so as to form an asymmetrical state with the first rotating shaft 410 as the center, and at least one empty rotating shaft 420 can be formed protruding in a part of the periphery, so that the rotating plate 500 described later is attached to the periphery.

[0078] A rotating protrusion 430 may be formed on the opposite side surface of the first rotating shaft 410 of the first rotating plate 400, for rotating the object 1 so that it is fixed in a suspended state.

[0079] The second rotating plate 600 is a component that is combined with the first rotating plate 400 on the boss 210 of the head 200 and connected to the drive unit 300. When the drive unit 300 is activated, it rotates in the opposite direction to the first rotating plate 400 to attract the attention of young children.

[0080] This second rotating plate 600, as Figure 5 As shown in the figure, it can be made into a circular plate of a predetermined size, and is rotatably connected to the boss 210 of the head 200 via a second rotating shaft 610 that protrudes from the back and is coaxial with the first rotating shaft 410 of the first rotating plate 400, and then connected to the drive unit 300.

[0081] Here, the second rotating shaft 610 protrudes from the back of the second rotating plate 600 in a tubular shape and is then attached to the boss 210 of the head 200. The first rotating shaft 410 protrudes from the back of the first rotating plate 400 in a rod shape and is attached to the boss 210 in a state of being inserted into the second rotating shaft, thus forming a coaxial structure with the second rotating shaft 610.

[0082] The second rotating plate 600 can be formed with the second rotating shaft 610 in an eccentric state so as to form an asymmetrical state with the second rotating shaft 610 as the center, and can be made of a translucent material with a different color than the first rotating plate 400.

[0083] Subsequently, as the first rotating plate 400 and the second rotating plate 600 rotate in opposite directions via the drive unit 300, a portion of them can intersect each other. At this time, the translucent materials of different colors intersect and overlap to provide mixed colors, thereby attracting the attention of young children.

[0084] For example, when the first rotating plate 400 and the second rotating plate 600 rotate in opposite directions, such as Figure 9As shown in the diagram, a portion can overlap with the narrowest possible area, and as... Figure 10 As shown in the diagram, a portion can overlap with the widest area.

[0085] Here, for example, when the first rotating plate 400 is a blue translucent plate and the second rotating plate 600 is a yellow translucent plate, the overlapping area can appear as grass green. Consequently... Figure 9 As shown in the diagram, when the first rotating plate 400 and the second rotating plate overlap with their narrowest area, they can provide three colors: blue, grass green, and yellow. Figure 10 As shown in the diagram, when the first rotating plate 400 and the second rotating plate 600 overlap with their widest area, a grass green color can be provided.

[0086] Here, the automatic rotating device 10 for toddlers according to one embodiment can be manufactured with the second rotating plate 600 removed.

[0087] Drive unit 300 Figure 5 As illustrated, it is located inside the head 200 to provide rotational force, specifically, as shown in the figure. Figure 6 and Figure 7 The diagram shows a drive motor 310, a first sprocket 320, a second sprocket 330, and a gear system 340.

[0088] Drive motor 310 Figure 7 As shown in the figure, it is installed in the mounting space of the head 200 in a state of being built into the motor housing 311, and is provided with rotational force by being turned on and off by the power input.

[0089] The first sprocket 320 is a component that rotates the first rotating shaft 410 of the first rotating plate 400 by starting the drive motor 310.

[0090] This first sprocket 320 is made in the form of a spur gear and can be fixed to the first rotating shaft 410 of the first rotating plate 400, which is attached to the boss 210 of the head 200, in the mounting space of the head 200. It is connected to the drive motor 310 through the gear train 340 described later, so that the first rotating plate 400 rotates at the same time as the drive motor 310 starts to rotate.

[0091] The second sprocket 330 is a component that rotates the second rotating shaft 610 of the second rotating plate 600 by starting the drive motor 310.

[0092] This second sprocket 330 is made in the form of a spur gear and can be fixed to the second rotating shaft 610 of the second rotating plate 600, which is attached to the boss 210 of the head 200, in the state of being installed in the mounting space of the head 200. It is connected to the drive motor 310 through the gear train 340 described later, and thus the second rotating plate 400 rotates as the drive motor 310 starts to rotate.

[0093] The gear system 340 is a component that uses the drive motor 310 to make the first sprocket 320 and the second sprocket 330 rotate in opposite directions, thereby causing the first rotating plate 400 and the second rotating plate 600 to rotate in opposite directions.

[0094] This gear system 340 can be composed of multiple spur gears meshing with the first sprocket 310 and the second sprocket 300 respectively, so that the rotational force of the drive motor 310 is transmitted to the first sprocket 310 and the second sprocket 300 respectively. Furthermore, the gear system 340 can be arranged with spur gears that can change direction, so that the spur gears meshing with the first sprocket 310 and the second sprocket 300 can rotate in opposite directions.

[0095] Subsequently, the first rotating plate 400 and the second rotating plate 600 can rotate in opposite directions via the first sprocket 320 and the second sprocket 330, which rotate in opposite directions along with the gear system 340 when the drive motor 310 is started. As the first rotating plate 400 and the second rotating plate 600 rotate in opposite directions, they attract children to concentrate by overlapping due to a partial intersection.

[0096] The rotating plate 500 is a component that provides a fixed part for the rotating object 1 and revolves around the head 200 together with the rotating object 1 as the first rotating plate 400 rotates. During the revolution, the rotating object 1 rotates around the empty rotation axis 420 by the weight of the rotating object 1, thereby causing the rotating object 1 to rotate.

[0097] Specifically, rotating the rotating plate 500 is as follows: Figure 5 and Figure 6 As shown in the figure, a portion of the device has a rotating fastener 510, which fixes the rotating object 1 in a suspended state and is rotatably attached to the empty rotating shaft 420 protruding from the first rotating plate 400. When the first rotating plate 400 rotates, the rotating object 1 and the device revolve together around the head 200. During the revolution, the device can rotate around the empty rotating shaft 420 by gravity caused by the weight of the rotating object 1 acting according to its position.

[0098] Here, the base portion 100 supports the head 200 by a connecting rod 130 that bends with a predetermined curvature, thereby causing the rotation trajectory of the first rotating plate 400 and the rotating plate 500 to be inclined relative to the ground.

[0099] Subsequently, as the first rotating plate 400 rotates, the rotating plate 500 revolves around the head 200 along the rotation trajectory of the inclined first rotating plate 400. The height of the rotating object 1 changes with the position of the revolution. At this time, it can rotate idly around the empty rotation axis 420 by gravity acting with the height of the rotating object 1.

[0100] Therefore, as the rotating object 1 rotates around the head 200 along with the rotation of the first rotating plate 400, it also attracts the child's attention by rotating the empty rotation of the rotating plate 500.

[0101] In addition, rotating the rotating plate 500 is to smoothly rotate the weight of the rotating object 1 in the empty rotation, forming an asymmetrical state with the empty rotation axis 420 as the center, and then combining it in an eccentric state relative to the empty rotation axis 420.

[0102] Consequently, the rotating plate 500 is tilted to one side, so the rotating object 1, which is positioned according to the revolution, can smoothly rotate in the air under the action of gravity.

[0103] The operation and function of an automatic rotating device 10 for toddlers according to an embodiment including the components described above are explained below.

[0104] The drive motor 310 starts rotating when the power supply is input, which in turn causes the gear system 340 to rotate.

[0105] The gear train 340 consists of multiple spur gears that rotate in conjunction with the drive motor 310, causing the first sprocket 320 and the second sprocket 330 to rotate in opposite directions.

[0106] The first rotating plate 400 rotates together with the rotating plate 500 while the first sprocket 320, which is fixed on the first rotating shaft 410, rotates in one direction.

[0107] The rotating object 1 is suspended on the rotating plate 500 and revolves around the head 200 together with the moving rotating plate 500.

[0108] Here, the rotating object 1 tilts along the rotation trajectory of the first rotating plate 400 via the curved connecting rod 130, and its height changes during the revolution. When the rotating object 1 is at a high position during the revolution, it moves to a low position by gravity due to its weight, while the rotating plate 500 rotates in vain.

[0109] Subsequently, as the first rotating plate 400 rotates, the rotating object 1 will revolve around the head 200, attracting the children's attention as the rotating plate 500 rotates in the air.

[0110] On the other hand, the second rotating plate 600 rotates in the opposite direction to the first rotating plate 400 while partially intersecting the first rotating plate 500, thanks to the rotation of the second sprocket 330 fixed to the second rotating shaft 620.

[0111] Here, the first rotating plate 400 and the second rotating plate 600 are formed of translucent materials of different colors, so the color of the intersection changes, thereby attracting the attention of young children.

[0112] The music box 150 is activated by a control button and plays a set piece of music. The nursing lamp 250 emits light and provides illumination via a control button located on the music box 150.

[0113] As described above, according to one embodiment of the automatic rotating device 10 for toddlers, while the rotating plate 500 connected to the rotating object 1 revolves through the drive unit 300, the rotating plate 500 can also be rotated in the air by the weight of the rotating object 1, thereby maintaining the toddler's concentration.

[0114] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
